Movable connection for line sections

Abstract

Movable connection between each time two parts of at least one line and a support construction substantially parallel therewith and connected thereto to enable a pivoting movement substantially about a longitudinal axis parallel to the longitudinal axes of the interconnected parts, whereby between each time the two parts there is disposed a known per se revolving piece, enabling a pivotal movement about the through-longitudinal axis of the part connected by the revolving piece, at least two revolving pieces being mounted on a common longitudinal axis and in longitudinal direction in spaced apart and tandem relationship.

I claim: 
     
       1. Apparatus comprising: at least one pipe line having two portions connected end-to-end by a first revolving piece which permits relative rotation of the two portions about a rotation axis which is the same as the longitudinal axis of at least one of the portions; and a pipe-line support structure extending substantially parallel to said pipe line portions and connected thereto, said support structure having two portions connected end-to-end by a second revolving piece which is longitudinally spaced from said first revolving piece, said second revolving piece permitting relative rotation of the two support structure portions about a common rotation axis that is the same as the rotation axis of the pipe line portions. 
     
     
       2. Apparatus as in claim 1 wherein one of said pipe line portions is straight and wherein said common rotation axis coincides with the axis of said straight portion. 
     
     
       3. Apparatus as in claim 2 wherein the other of said pipe line portions includes a straight section having an axis which coincides with said common rotation axis and an offset section adjacent said first revolving piece. 
     
     
       4. Apparatus as in claim 1 wherein said common rotation axis coincides with the axis of one of said pipe line portions and with the axis of one of said support structure portions. 
     
     
       5. Apparatus as in claim 1 including a bracket between at least one pipe line portion adjacent one of the revolving pieces and the adjacent parallel portion of said support structure, said bracket extending to beyond the respective revolving piece in the direction of the other revolving piece. 
     
     
       6. Apparatus as in claim 1 wherein said support structure includes at least one pipe line. 
     
     
       7. Apparatus as in claim 1 wherein at least one of the revolving pieces is provided with a rinse water connection which is connected to one of the pipe line portions. 
     
     
       8. Apparatus as in claim 1 wherein said pipe line includes a straight main line interrupted by an offset portion which is connected at its ends to said main line by bends and wherein the axis of said main line coincides with said common rotation axis.
